도 3은 본 발명에 따른 증기조리장치의 관로 내부를 보인 평단면도이고, 도 4는 본 발명에 따른 증기조리장치의 증기주입부를 통해 증기가 통과하는 상태를 보인 도2 IV의 확대도이다. 본 발명에 의한 증기조리장치의 증기주입부에는 도 3, 도 4에 도시된 바와 같이, 관로면적축소판(23)과 이를 지지하는 지지대(25), 안내기둥(22)이 설치되어 있다.Figure 3 is a plan sectional view showing the inside of the pipeline of the steam cooking apparatus according to the present invention, Figure 4 is an enlarged view of Figure 2 IV showing a state that the steam passes through the steam injection unit of the steam cooking apparatus according to the present invention. As shown in FIGS. 3 and 4, the steam injection unit of the steam cooking apparatus according to the present invention is provided with a pipe area reduction plate 23, a support 25 supporting the same, and a guide pillar 22.

관로면적축소판(23)과 관로(21)의 사이에는 관로면적축소부(24)가 형성되는데, 이는 증기발생장치(20)로부터 관로(21)를 통해 유도된 증기의 속도를 증가시키기 위한 것이다. 장애물없이 관로(21)를 통해 이동하던 증기는 급격한 관로(21) 내부 면적의 축소로 인해 관로면적축소부(24)를 지난 후 압력이 감소하고 속도가 증가하는 변화를 거치게 된다. 이러한 변화는 베르누이법칙으로 설명되며, 속도 증가에 따라 증기의 운동에너지가 급격히 상승하게 된다. 이러한 관로면적축소부(24)는 관로(21)의 중심부를 폐쇄하고 그 주변을 개방시키는 방법으로 형성시키는 것도 가능하나 관로(21)의 중심부를 개방하고 관로(21)의 내벽에 접하도록 폐쇄부를 형성시키는 것도 가능하다. 또한 조리개나 밸브 등의 구조를 이용하여 관로면적축소부(24)의 면적을 사용자의 조작에 의하여 조절될 수 있도록 구성하는 것도 가능하다. 관로면적축소부(24) 상측에는 안내기둥(22)이 설치되는데 관로면적축소부(24)에서 증가한 증기의 운동에너지가 감소되기 전에 안내기둥(22)을 통과하도록 하기 위해서는 관로면적축소부(24)와 안내기둥(22)이 인접하도록 설치하는 것이 바람직하다. Between the conduit area reduction plate 23 and the conduit 21, a conduit area reduction part 24 is formed, which is to increase the speed of the steam induced through the conduit 21 from the steam generator 20. The steam moving through the conduit 21 without obstacles undergoes a change in which the pressure decreases and the speed increases after passing the conduit area reduction part 24 due to the rapid reduction in the inner area of the conduit 21. This change is explained by Bernoulli's law, and as the velocity increases, the kinetic energy of steam rises rapidly. The conduit area reduction part 24 may be formed by closing the center of the conduit 21 and opening the periphery thereof, but the closed part may be opened to open the center of the conduit 21 and contact the inner wall of the conduit 21. It is also possible to form. In addition, it is also possible to configure the area of the pipeline area reduction portion 24 to be adjusted by the user's operation by using a structure such as an aperture or a valve. A guide column 22 is installed above the pipeline area reduction part 24, but in order to pass through the guide column 22 before the kinetic energy of the steam increased in the pipe area reduction part 24 is reduced, the pipeline area reduction part 24 is provided. ) And the guide pillar 22 are preferably installed adjacent to each other.                     

안내기둥(22)은 증기가 조리실(11) 내부의 각 부분으로 고루 분사되도록 유도하는 역할을 하며 스테인레스강을 프레스 작업함으로써 제조되며 관로(21)의 폐쇄면(21a)에 설치된다. 안내기둥(22)의 크기, 모양, 위치, 방향, 개수는 조리실(11)의 크기와 형태에 따라 적절하게 선택할 수 있는데, 본 실시례에서는 4개의 안내기둥(22)이 각각 동일한 거리를 두도록 구성하였다. 안내기둥(22)의 각각은 서로 다른 부위를 향하도록 하여야 조리실(11) 전체가 균일하게 가열되도록 할 수 있으며, 도 3에 도시한 바와 같은 곡선형태로 제작하면 증기가 조리실(11) 내부에서 시계반대방향의 나선형으로 유동하도록 할 수 있을 것이다. 또한 안내기둥(22)을 불규칙적인 곡면을 갖도록 형성하면 증기가 안내기둥(22) 내부를 통과하는 도중 유동에 의하여 운동에너지가 증가하도록 할 수 있으며, 이전에 증기의 유동이 비교적 층류였던 경우라도 난류로 변화되어 조리실(11) 내부로 균일하게 분사된다. 또한, 관로면적축소부(24)와 안내기둥(22)을 통해 2중으로 속도가 증가하게되므로 더더욱 난류 발생율이 높아지게 되고, 별도의 송풍수단없이 효과적으로 증기를 공급하는 기능도 기대할 수 있다.The guide column 22 serves to induce steam to be evenly sprayed to each part inside the cooking chamber 11, is manufactured by pressing stainless steel, and is installed on the closed surface 21a of the conduit 21. The size, shape, position, direction, and number of the guide columns 22 may be appropriately selected according to the size and shape of the cooking chamber 11. In this embodiment, the four guide columns 22 are configured to have the same distance from each other. It was. Each of the guide columns 22 should be directed to different parts so that the entire cooking chamber 11 can be uniformly heated, and if it is manufactured in a curved shape as shown in FIG. 3, steam is clocked inside the cooking chamber 11. It may be able to flow in an opposite spiral. In addition, when the guide column 22 is formed to have an irregular curved surface, the kinetic energy can be increased by the flow while the steam passes through the inside of the guide column 22, and even if the flow of the steam was relatively laminar, the turbulent flow It is changed to and uniformly sprayed into the cooking chamber (11). In addition, since the speed is increased by double through the pipe area reduction part 24 and the guide pillar 22, the turbulence rate is further increased, and a function of effectively supplying steam without a separate blowing means can be expected.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 증기조리장치는 안내기둥에 의하여 조리실 각부에 증기가 균일하게 분사되도록 구성함으로써 음식물의 크기나 위치와 관계없이 균일하게 가열 할 수 있는 효과가 있다. As described in detail above, the steam cooking apparatus according to the present invention has an effect that can be uniformly heated regardless of the size or position of the food by being configured so that the steam is uniformly sprayed to each part of the cooking chamber by the guide pillar.

또한 본 발명에 따른 증기조리장치는 관로 면적 축소부와 안내기둥에 의해 증기의 유동을 층류에서 난류로 전이시킴으로써 조리실 내부의 각부분으로 증기가 균일하게 도달하게 할 수 있다.In addition, in the steam cooking apparatus according to the present invention, the steam flow can be uniformly reached to each part inside the cooking chamber by transferring the flow of steam from the laminar flow to the turbulent flow by the pipe area reducing part and the guide pillar.
